> matching
Small change I guess can be done while integration:
"app/testpmd: support matching reserved filed for VXLAN"
>
> Add a new testpmd pattern field 'last_rsvd' that supports the
> last 8-bits matching of VXLAN header.
>
> The examples for the "last_rsvd" pattern field are as below:
>
> 1. ...pattern eth / ipv4 / udp / vxlan last_rsvd is 0x80 / end ...
>
> This flow will exactly match the last 8-bits to be 0x80.
>
> 2. ...pattern eth / ipv4 / udp / vxlan last_rsvd spec 0x80
> vxlan mask 0x80 / end ...
>
> This flow will only match the MSB of the last 8-bits to be 1.
